Do you flush? Do you kill the lights prior to harvest?

Thank you for the votes. I'm more curious about the last dark 48. My next harvest will be the first time I try it.

Some swear by doing the lights out thing.
I do it. but, really haven't notice any change I could detect.
I think the jury is still out on the light thingy.
Good luck

Would you stop feeding a pregnant woman 2 months before her due date???
No, so why would you stop feeding your plants for the last quater of it's flower (fattening) period.

I'm no scientist or anything but I think it's because when you keep feeding it until harvest it'll be bound to be full of unused nutrients the plant didn't put to use. So some is wasted & I believe it makes it more harsh(idk if drying and curing will get it out of the bud or allow the bud to put it to use)
This is all just what I'm assuming though so anyone can correct me if its been proven that the plant uses all of the ferts by the time you're smokin it with no flush or without only water for the last week or 2.

Nutrients are not stored in the calyxes (buds).
Nutrients are used up very quickly when they are transported around the plant, especially in the calyxes.
Nutrients are 'stored' in the roots, stem(s) and the leaves.
It takes a lot of overfeeding (the plant would be visibly damaged and probably beyond saving) to get a nutrient build up in the calyxes.
The dry & cure is what determines the quality of the final product.
Do it wrong and you can end up ruining your crop.
Do it right and you can enhance flavour, odour, appeal etc.

yep, when following a professionally mixed nutrient system, one will notice that the charts will show a decreasing amount of nutrients as the flowering schedule comes to an end. Usually starting at mid flowercycle, the decrease generally ends with zero nutrients in the chain.....If following the directions, no "formal flushing needs to occur", unless of course you're one of those who pack in the poison(PK boosters) for profit., then a formal flush is necessary.
That is called flushing, by any other name, still flushing.

Nothing you described is flushing, its just proper feeding. With proper feeding you're giving the plant only what it needs and you'll never end up with "zero nutrients". When people flush plants they are trying to rid the reservoir or grow medium of all nutrients right down to 0 ppm or as close to it as possible, which will starve the plant and hinder growth in its final stages. The only time you ever want to actually flush is when you have over fed the plant, with proper feeding there is no need to flush.
The final week before harvest my nutrient solution is down to about 400 ppm, no flush needed.

Thanks to all that replied. Even though opinions differ, we are all trying to enhance the quality of cultivated bud. It's all good, and eventually the truth comes out.
When I was growing outdoors back in the 70's (we had shit for lights), the one trick that a lot of growers believed in was pulling the plant up (not all the way), but just enough to "shock" the plant. Supposedly, the plant feels death befalls it, and it sends more resins to the colas as an emergency response to save the plant long enough to be pollinated and drop seeds.
That didn't last long!

This debate has and will go on as long as ganja exists. Do what ever you like.
Ive experimented ALOT with this. Flushing and Extended Dark periods.
I use FFOF soil.
I was growing more indica dominant plants that could handle heavy feedings so I used all Fox Farms Nutes and the Tri-Pack of bud boosters.
I would flush for the last 14 days - every 4 days, and get perfect smoking buds with a pure taste.
This time Im growing sativa dominant plants in their 5th week of flower and havent fed them 1x. I just give them Cal-Mag+ and PH the water to 6.0....I will only give them 1 flush.... 2 weeks before harvest.... to get out any salt or junk in the soil and give straight water thats not ph balanced until harvest.
Its mostly strain dependant. BCBD Purps has to be flushed with straight water for the last 2 weeks and cured for atleast a month if its gonna smoke in a joint without black ash and charcoal chunks falling off the end of the joint. But hands down..... their is NO TASTIER weed on the planet that can beat BCBD Purps done right.
Great White Shark increases trichome production by 20% if put in the dark for 3 days and flushed with ice-cold water to "shock the roots" which forces the plant to push out every last drop of resin to protect itself. Its all up to the grower, strain, and style of grow.

Well I don't know about this..
1. Nutrients are 'stored' in the roots, stem(s) and the leaves. Not in the buds,, Mmmm
Nuts are stored in the in buds to.. not just in stem's and roots.. I know its not talked about, for obvious reasons, everybody likes to get good light on there buds, why cause they absorb light not as much as the leaves but They still absorb light, and distribute that energy Light, to feed itself.. They need food for this Photo senses. There is not one part of your plant that does not absorb nuts... You can't use steroids on your plant for 4-5 months, and expect to get all of it out with a 2 week flush. flushing might make the weed taste better. But the nuts are still in the plant.. Just ask any farmer that grows corn or strawberries for a living... That's why great soil is important not great nuts.. The best tasting plants with any controversy wether it be corn grapes avocados, comes from good fresh soil.. That"s why in grocery stores here in Colorado will have steroid fruit will be one price. and organic produce another price.. Its the same way with weed, there is steroid weed. and then organic..
I bet in the the future dispensaries will have 2 sections one organic and one for steroids..

What? I'm not quite sure what your point is or how you came to the conclusion.
Please provide the scientific information you have on how nutrients are stored in the calyxes.
I have linked to a scientific study (conducted by educated scientists) on nutrient storage in plants, in a different thread on the topic of pre-harvest flushing, it's readily available for you to read.
It explains rather well how and where nutrients are stored in plants and how quickly these nutrients are used up.
Nutrients are mainly stored in the roots and stems, with a somewhat significant storage in the leaves as well.
I'd like to stress that we're talking about storage here, not usage or where nutrients are transported to/are used.
It also explains how yield relates to deficiencies, abundances and critical (optimum) feeding schedules.
If you over- or underfeed you will end up with a worse yield than you could have had you stayed @ critical feeding levels.
It also reveals how the nutrient levels will be in percentages, in the various areas of the plant with regards to deficiency, abundance and critical feeding.
Why are you talking about photosynthesis (I assume that's what you meant)?
Steroids? Why are you talking about using steroids and flushing those steroids out?

If i switch from synthetic based nuts to all organic for the last couple weeks while I use a flushing agent will that work effectivly to flush AND not starve the plants? because I was under the impression that its unneccesary to flush with organics? Its a recirculating system so I was assuming that while the final flush does its thing the BioThrive bloom will do its organic thing and I can get the best of both worlds.
Yes I know there are a lot of views on not flushing, but i'm not ready to try that until i've finished doing my own taste test. which I am. but in the mean time I would like advice on what i'm currently attempting.
Also does anyone know if you don't need to ph balance biothrive bloom?

great post.... And I totally agree. The last two weeks is when you should be boosting the crap out of her.. I do believe that a final flush product should be used to get all the unused nutes out tho

Most street smokers don't know their arse from their elbow when it comes to weed. As long as it stinks to high heaven and is covered in THC, they are happy as a pig in shit and will come back for more. It is your more discerning smoker that will be able to taste and critique your weed.
A good cure works wonders but I aint selling weed thats 1-2 month cured, why would I? Do I get any extra money for my extra work..... No.
I yeild around 2 Kg a pop, am I gonna keep that in my house for months to cure and have another grow on, not on your nelly, the feds would throw the book at me if they popped round for a cup of tea and a biscuit.
I flush nothing although I do give just water every 3-4 feeds. 60+ oz goes in a week and they love it, the rest goes into cure for percy. Essentially it is only experienced grower and dealers that know the difference in quality.
